View Full Version : G55VW - Fan rpm to slow?

10-03-2012, 09:39 AM
Hello. I have a g55vw and i am a little bit worried about the temperature readings. In full stres (intel burn test) the cpu got
very hot, about 90-95C and the fan was only going at 3350-3400 rpm, according to speedfan.
Is this normal?
Should't the fan speed be higher under such heavy stress? Here's a picture o the readings.12219

I've read the topics that some g55's get pretty hot, but my main concern is the fan speed. In idle i can barely hear it...

Sounds kinda normal.

Please use the same tools as the rest of us to have a closer reference. Prime95 maximum heat + HWiNFO64.

State room temp, laptop enviroment, BIOS.

I've downloaded prime95 (64bits edition) but i'm kind of newbie and i don't know what test to chose... Could use some help...

Even so, shouldn't the fan rpm's be higher?

So i've managed to start the test with prime95
I've selected the "in place large FTT s (maximum heat, power consumtion, some RAM tested)"
It got a max temp of 96C, measured with hwinfo64....
Please tell me something about the fan rpm...

Can anyone plese tell what speed does the fan goes on full load on their computer? (g55)
Come on people, a little help please!!!

As @c_man replied less than an hour after your OP, your temperature results and fan speeds appear normal. A 96 C maximum is a little on the high side, but may not be unusual if your ambient room temperature is 30+ C. 3500 RPM is the maximum fan speed I've seen reported for these systems.

Thermal paste application on the GPU and CPU can vary from machine to machine, resulting in slightly different temperature results. It also depends on your ambient room temperature, since the cooling occurs only by fans blowing ambient temperature air over the components. You are running stress tests to maximize CPU and GPU use, so if you don't shut down or get video artifacts, your testing was successful.

I've never seen temperature information related to fan speed posted as to the exact temperature the fans spin at maximum. I suspect this is because it is controlled by the BIOS and not accessible to users.

This is my G55 doing one hour of Prime95 and some Furmark sessions during that. Room temp 32C. Flat surface with holes in it, not very good back clearance.

96 is not great, but not that bad either.

Good Post, @c_man! When reporting temperatures, it's important to note 1) what's running on the laptop, 2) the ambient room temperature, and finally, 3) the CPU/GPU temperature values.
